Facebook bans firm behind Pfizer, AstraZeneca smear campaign

Facebook said Tuesday that it has removed hundreds of accounts linked to a mysterious advertising agency operating out of Russia that sought to pay social media influencers to smear COVID-19 vaccines made by Pfizer and AstraZeneca.

A network of 65 Facebook accounts and 243 Instagram accounts was traced back to Fazze, an advertising and marketing firm working in Russia on behalf of an unknown client.
